Answer:the negative particles are electrons which are smaller and weigh less than the proton
Explanation:
Explanation:
Webb gives us new and unique eyes of places that we have never been able to reach.” With NASA and the European Space Agency's Hubble pushing 32 years in orbit, the bigger, 100 times more powerful Webb is widely viewed as its successor even though the two are vastly different.
Answer:
Explanation:
Impulse on an object is given by ![\mathrm{[impulse]}=F\Delta t](https://tex.z-dn.net/?f=%5Cmathrm%7B%5Bimpulse%5D%7D%3DF%5CDelta%20t)
.
However, it's also given as change in momentum (impulse-momentum theorem).
Therefore, we can set the change in momentum equal to the former formula for impulse:
.
Momentum is given by 
. Because the truck's mass is maintained, only it's velocity is changing. Since the truck is being slowed from 26.0 m/s to 18.0 m/s, it's change in velocity is 8.0 m/s. Therefore, it's change in momentum is:
.
Now we plug in our values and solve:
(two significant figures).
The answer is 27.03 I just multiplied the two numbers
The answer is D.
C and A are incomplete as they only treat specific types of energy, and B doesn't answer the question.
